This is the strongest [Frost Prime] Snow Globe build you can ever create, a real monster, tank over tanks, the strongest.
So... why potentially? Well, you have to gain buffs from three mods - [Energy Conversion] and [Growing Power] BEFORE you activate Snow Globe. And your three team mates have to wear [Power Donation] Aura :) But even without [Power Donation] Aura, this is the strongest build.
If you think that this is too much for that skill, replace something with augment or Stretch mod.
Suggested Arcanes are Guardian, Ultimatum / Energize :)
